Contactor adds high-voltage latching capability

TE Connectivity has extended its KILOVAC CAP120R contactor family with a new high-voltage latching configuration. Applications include defense, marine, urban air mobility (UAM), unmanned aerial vehicle (UAV) commercial and military/aerospace applications that require lightweight latching coils and reduced power consumption.

Targeting an industry need for higher voltage isolation, smaller size and weight, and lower power consumption, the 150-amp DC contactor includes single-pole, hermetically-sealed auxiliary contacts with a latching actuator mechanism, which allows for low-power consumption uses, said TE. The hermetically-sealed design enables the contactor to operate in harsh environments.

The high-voltage device can be used in power distribution, energy storage, and battery systems. Key specs include an operating temperature range of  -40°C to 85°C, a voltage maximum of 600 VDC, and a mechanical life (minimum) of 100,000 cycles.

Key specs include withstand high break levels of 1,000 A at 400 VDC and 600 A at 600 VDC. The dielectric withstand voltage terminal-to-terminal is 1 mA max @ 2800 Vrms and 1 mA max @ 1500 Vrms terminal-to coil.

The contactor allows installation flexibility through bidirectional load switching, said the company. The contact arrangement is SPST-NO, Form P, and the main contacts are not polarity sensitive. The contactor weighs 0.14 kg.
